Wanted: Dart/Scamp parts

Hey guys, I was going through my window regulator stuff, and realized I also need a part for the rear side window regs. The roller pieces that are I guess dumbell shaped. I think they are just called rollers in the parts manual. I can't tell from the manual on CD I got off of eBay. The pages lost some detail when they scanned them. Anyway, they are two rollers, side by side. If anyone has a pair in good shape, I'd be eternally grateful. Thanks for all the replies.
